On that note, can someone explain the difference between the fragment setting and the min_average
size setting? We have had this overflow issue when setting the fragment size to 2M and the
min_average to 10M or larger. If I set the fragment size higher than 2M the traffic server
performance falls off a cliff or stalls out completely.
At the moment I have both set to 2M and have not seen the issue resurface although it's too
early to tell.
_stats reports that I have a max of 1M direntries with the above config.

the default of 8KB average size creates way too many directory entries (wasting memory, disk
I/O and longer startup times). They should estimate how many objects they need, salt it appropriately,
and tune the config accordingly.
